Date Items in rich:pickList

I make use of the RichFaces component rich:pickList to provide a list of Date objects which can be selected

When the data gets validated the JSF page shows a validation error: "Validation Error: Value is not valid". I know, the Date Object is somehow not converted. But I don't know why? First I tried setting the attribute dateConverter:

converter="#{javax.faces.convert.DateTimeConverter}"

This didn't work. Afterwards, I added the following statement:

<f:convertDateTime pattern="MM/dd/yyyy" />

Didn't solve the issue either.

Btw: What is the difference of both ?

Please find below the whole source code:

}

No exception is thrown on server side.

Could somebody help, please ? This would be great! Thanks in advance!

I found the solution in another post:JSF 2 - f:selectItems with a Date keyed Map

Don't know why I didn't find this post beforehand..
